Subject: [RE-XMIT] Update orinoco driver to 0.13e
Date: Thu, 29 May 2003 12:58:33 +1000 [thread overview]
Message-ID: <20030529025833.GF2058@zax> (raw)
Linus, please apply. The patch below updates the orinoco driver,
fixing many bugs and adding some minor features. It also adds a new
module, orinoco_tmd for devices based on the TMD7168 PCI<->PCMCIA
adaptor.

+ * orinoco_tmd_pci_id_table near the end of the file. If you have a
+ * card we don't have the PCI id for, and looks like it should work,
+ * drop me mail with the id and "it works"/"it doesn't work".
+ *
+ * Note: if everything gets detected fine but it doesn't actually send
+ * or receive packets, your first port of call should probably be to
+ * try newer firmware in the card. Especially if you're doing Ad-Hoc
+ * modes
+ *
+ * The actual driving is done by orinoco.c, this is just resource
+ * allocation stuff.
+ *
+ * This driver is modeled after the orinoco_plx driver. The main
+ * difference is that the TMD chip has only IO port ranges and no
+ * memory space, i.e. no access to the CIS. Compared to the PLX chip,
+ * the io range functionalities are exchanged.
+ *
+ * Pheecom sells cards with the TMD chip as "ASIC version"
